T0 to whom zit may concern.-

Beit known that I, GEORGE E. RoUeHLEY, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inExtension-Tables, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to improvements in extension-tables, and especiallyto that class of such tables in which the supplemental leaves are storedbeneath the table-top in such a manner as to be readily accessible whenthe table is extended; and its object is to provide simple and compactmechanism for guiding the leaves, so that they will be moved out ofcontact with each other when lowered, and mechanism for rigidlysupporting the leaves to prevent their getting out of line with the topor varying, it being also an object of this invention to so arrange andconstruct. the leaves that when they are in place for use the top andits side rails will present a continuous and unbroken outline, saidleaves being the same length as the top and each provided with attachedrail-sections.

To this end the invention consists in securing to the under side of theleaves downwardly-projecting supporting members or arms to engageguide-slots in plates secured to the extension-slides or table-frame,the

slots engaged by the arms on one leaf being inclined downward in adirection opposite to that of the slots for the arms of the opposingleaf, so that as the arms pass down the slots the leaves will be movedapart, and the upper ends of said slots are formed with lateralextensions or recesses to receive the arms when the leaves are up andsecurely hold the same in that position; and the invention consists inthe particular construction of the side rails, whereby when the leavesand their attached rail-sections are lowered they may be moved laterallybetween the fixed portions of the side rails, the invention alsoconsisting in providing certain other new and useful features, all ashereinafter more fully described, and particularly pointed out in theclaims, reference being had to the accompanying drawings, in which-Figure 1 is a transverse vertical section on the line 1 1 of Fig. 2 of adevice embodying my invention; Fig. 2, a longitudinal section on theline 2 2 of Fig. 1. Fig. 3 is a sectional detail of one of thesupporting-arms and its slotted plate; Fig. 4 a plan view of one of theconnecting-catches. Fig. 5 is a transverse vertical section showingamodified construction. Fig. 6 is a side elevation showing a modifiedform of side rail; Fig. 7, a transverse vertical section of the same.Fig. 8 is an inverted plan view of a modified form of table, and Fig. 9a section of the same on the line 9 9 of Fig. 8.

A is the fixed table-top, which is supported by the outwardly anddownwardly inclined side and end rails B, which rails are secured attheir lower edges to the transverse supporting-strips G and C, to whichthe tablelegs D are secured. To the upper side of these strips and at adistance from the side rails are secured the extension-slides E, themember E of each slide being secured near its middle to the strips 0,and the other members E whose ends abut at the center of the table, aresecured at one end to the strips 0 at each end of the table and slideupon the dovetail connecting-bar E the strips, legs, andextension-slides forming the supportingframe of the table.

F F are the supplemental leaves, which are of a length and formed attheir ends to match the table-top, rail-sections G, corresponding inform to the side rail B, being secured to the ends of the leaves. Theserail-sections G are divided longitudinally into two parts,

which are hinged together, so that the lower half G may be folded inwardupon the upper half to allow the same to be moved inward beneath thetable-top and over the sup porting-strips 0 when the leaf is in itslowered position and the table closed, suitable stops G being secured tothe side rails to engage the inner sides of the rail-sections G when theleaf is in place and hold the same in line with the side rails. Securedto the under side of each leaf and adjacent to the outer side of eachmember E of the extension-slides is a bracket H, havingdownwardly-extended arms H, forming supports for the leaf, on the endsof which arms are journaled the antifriction -rolls H and secured to theouter sides of the member E are the plates I, each provided with twopairs of downwardly-extendinginclinedslotsorguides I to receive therolls H The upper ends of the slots are extended laterally to formrecesses 1 to receive the antifriction rolls, a slight shoulder I beingprovided at the junction of the recesses and slots to prevent the rollsfrom being too easily disengaged from the recesses. Two of these extraleaves are provided at each end of the table, each plate I beingprovided with two pairs of slots, one pair for each leaf, which areinclined in opposite directionsthat is, each pair is inclined downwardtoward its end of the plate, so that when'the leaves are lowered byextending the table and moving the leaves to disengage the rolls fromthe recesses I the leaves will be separated as the rolls move down theinclined slots. This separating of the leaves allows one leaf to beraised at a time, as they will be disconnected-that is, when theordinary dowel-pin connection is used the dowel will be disengaged fromits socket in the opposite leaf. I prefer, however, to use theconnection shown, consisting of a plate J, slitted inward from one endto form the spring-arms J, said arms being curved so as to come nearlyin contact with each other near their outer ends and cut away at theirpoint of connection to the plate to form a socket toreceive a pin K,projecting downward from the lower side of the opposite leaf. Thus whenthe leaves are brought toward each other the pin K enters the slot andspringing the arms apart passes into the socket, where it is held by thespring action of said arms. The table is thus prevented from beingaccidentally pulled apart, as similar connections are provided betweenthe table-top and the leaves.

The bases of the brackets H extend transversely across the leaves towhich they are secured, and thus prevent said leaves from warping, andthe arms H form four supports for each leaf, thus rigidly supporting itin the plane of the table-top, the rolls by their engagement with therecesses I preventing the leaf from raising above such plane or droppingbelow it. The shoulders l prevent the rolls from being moved into theslots by the -extending of the table, and as the slots are inclined theleaves will not suddenly drop when the rolls enter the slots.

If desired, the rail-sections G may be hinged directly to the ends ofthe leaves, as shown in Fig. 5, instead of making them in halves, or bymaking a side rail having a scroll edge, as shown in Fig. 6, the widthof the rail-sections G is reduced, and it will not be necessary to hingethe sections at all, it being only necessary, if at all, to slightly cutaway the supporting-strips 0 near their ends.

Byinclining the side rails as shown the leaves, with their attachedrail-sections, will pass under the table-top and its attached side railsby simply dropping the leaves vertically downward a short distance,which not only throws the table-top and leaves out of the same plane,but the side rails and rail-sections as well.

In Figs. 8 and 9 the essential features of my invention are shownapplied to a round table, the extra leaves being inserted in the centerof the table-top instead of near each end, thus forming an ellipticaltable when the same is extended. In this construction short leaves F"are shown, to the ends of which are hinged the end sections F which areof such a length that when extended they form a continuous leaf of alength equal to the width of the table-top, and secured to their endsections are the rail-sections G The same mechanism is employed tosupport the leaves as in the other forms of table, and when they arelowered the end sections F are turned down, as shown in Fig. 9, so thatthe table-top may be closed thereover, and when the leaves are raisedthe end sections F are held in the plane of the table-top by the stops Fand F secured to the top and to the side rails, respectively.

Having thus fully described my invention, what I claim is- 1. Anextension-table comprising a top having a central and end sections, siderails on the central section, supporting means therefor,extension-slides consisting of inner members secured to the saidsupports, the central section being carried thereby, outer memberssecured to the end sections of the top, supplementary leaves providedwith rail-sections, means carried by said leaves for engagement with theouter members, said means comprising arms depending from the leaves,rollers carried thereby, and plates on the outer members, inclined slotsformed in said plates having recesses at their upper ends, shouldersformed between the recesses and slots, the rollers adapted to travel insaid slots, and recesses to carry the leaves to a position flush withthe table-top, substantially as described.
